2010-10-26AT91: pm: use plain cpu_do_idle() for "wait for interrupt"Nicolas Ferre2-2/+8
For power management at91_pm_enter() routine, use the cpu_do_idle() for a rock solid "wait for interrupt" implementation. For AT91SAM9 ARM 926 based chips, we can exceed the cache line length as we can access RAM even while in self-refresh mode. We keep plain access to CP15 for at91rm9200 as this feature is not available: instructions have to be in a single cache line. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
2010-10-26AT91: reset: extend alternate reset procedure to several chipsNicolas Ferre6-35/+12
Several at91sam9 chips need the alternate reset procedure to be sure to halt SDRAM smoothly before resetting the chip. This is an extension of previous patch "Fix AT91SAM9G20 reset" to all chips affected. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
2010-10-26AT91: reset routine cleanup, remove not needed icache flushNicolas Ferre4-58/+51
Generalize assembler reset routine to allow use on several at91sam9 chips. This patch replace double definitions of SDRAM controller registers and RSTC registers with use of classical header files. For this rework, we remove the not needed icache flush as it is already done in the calling function: arm_machine_restart(). Rename at91sam9g20_reset.S to generalize to several chips.

2010-10-20arm: remove machine_desc.io_pg_offst and .phys_ioNicolas Pitre33-70/+0
Since we're now using addruart to establish the debug mapping, we can remove the io_pg_offst and phys_io members of struct machine_desc. The various declarations were removed using the following script: grep -rl MACHINE_START arch/arm | xargs \ sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }' [ Initial patch was from Jeremy Kerr, example script from Russell King ] Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org> Acked-by: Eric Miao <eric.miao at canonical.com>
2010-10-20arm: return both physical and virtual addresses from addruartJeremy Kerr1-5/+3
Rather than checking the MMU status in every instance of addruart, do it once in kernel/debug.S, and change the existing addruart macros to return both physical and virtual addresses. The main debug code can then select the appropriate address to use. This will also allow us to retreive the address of a uart for the MMU state that we're not current in.

2010-10-08ARM: 6436/1: AT91: Fix power-saving in idle-mode on 926T processorsAnders Larsen1-4/+3
According to Atmel, their 926T processors (AT91 post RM9200) requires 'Wait for Interrupt' mode be entered right after disabling the processor clock in order to minimise current consumption when idle, so do both provided we're not running on a 920T (an RM9200). Furthermore, get rid of the #ifndef CONFIG_DEBUG_KERNEL, since arch_idle() can be turned off completely with the kernel parameter 'nohlt'.

Use a correct udelay value to get bus speed around 100KHz. The udelay value was most likely copied from the older devices, but the 9g45 is signicantly faster (400MHz, DDR, ..), so a udelay of 2 gives a bus speed of around 190KHz, which is too fast for some devices. A udelay value of 5 gives a bus speed of around 90KHz here.
